Explaining Sound Transmission Class

Explaining Sound Transmission Class

The sound transmission class (STC) is an integer rating for measuring and classifying how well a building wall or structure controls or reduces sound.

STC serves a critical role in the design and installation of HVAC systems, especially in terms of reducing noise (or keeping it to a minimum). In fact, marquee building standards such as LEED and WELL measure building noise levels as part of their scoring systems.
